The Formula Data type(Fx) output + A currency data type field/column in the calculated field to get a currency output.
I get the error even if my Total Selling Price in the calculated field is already a currency data type.
I also cannot use the formula data type(Fx) to get a currency field as the following error pops out, the alternative I do not get how to go about it, i.e Decimal(CurrencyField)
